1Combine the sweet pepper, garlic, onion, cilantro, and coriander powder in a food processor and blitz until smooth and uniform. Add salt to taste.
2Boil a large pot of water, then add the bouillon cube, salt, and pasta. Cook until al dente.
3Warm the cream in a medium pot over low heat until steaming, then whisk in the cold butter until melted. Gradually whisk in the shredded Gouda, cheddar, and Parmesan until smooth.
4Reserve 0.5 cup of cooking water and drain the pasta.
5Return pasta to the pot, add 1.5 tbsp of the seasoning paste, and toss to coat.
6Add the cheese sauce to the pasta and fold to combine, adding a splash of reserved pasta water if needed to loosen the consistency.
